Definitions

  • the present invention relates to regulating valves for a gas cooking appliance and to gas cooking appliances incorporating said regulating valves.
  • PRIOR ART Regulating valves for gas cooking appliances are known to comprise a rotating disc with a plurality of connecting holes, such that rotation of the rotating disc allows regulating the gas flow of the valve between an inlet conduit and an outlet conduit of said valve through said connecting holes.
  • US20040182456A1 describes a gas flow regulating device comprising a body with an inlet conduit through which gas is supplied, an outlet conduit, an inner cavity fluidically communicated with the inlet conduit, and a rotating disc arranged in the inner cavity of the body of the device, the rotating disc comprising a plurality of connecting holes for regulating gas flow between the inner cavity and the outlet conduit by means of rotation of the rotating disc.
  • the connecting holes overlap with an outlet hole of the outlet conduit, the rotating disc being movable along an angular path comprising an intermediate zone in which in all the angular positions the outlet hole overlaps with more than one connecting hole of the rotating disc, and the rotating disc comprising a main series of connecting holes increasing in size in the direction of increasing gas flow.
  • the object of the invention is to provide a regulating valve for a gas cooking appliance, and a gas cooking appliance incorporating said regulating valve, as defined in the claims.
  • the regulating valve of the invention comprises a valve body with an inlet conduit through which gas is supplied, at least one outlet conduit, an inner cavity fluidically communicated with the inlet conduit, and a rotating disc arranged in the inner cavity of the body of the device.
  • the rotating disc comprises a plurality of connecting holes for regulating gas flow between the inner cavity and the outlet conduit by means of rotation of the rotating disc, the connecting holes overlapping with an outlet hole of the outlet conduit.
  • the rotating disc is movable along an angular path comprising an intermediate zone in which in all the angular positions the outlet hole overlaps with more than one connecting hole of the rotating disc, and comprises a main series of connecting holes increasing in size in the direction of increasing gas flow.
  • the rotating disc of the regulating valve comprises between successive holes of the main series of connecting holes, and after each hole of said main series, a first intercalated hole, the size of each intercalated hole being smaller than the size of the preceding contiguous hole of the main series.
  • the rotating disc comprises a second intercalated hole between each first intercalated hole and the subsequent hole of the main series, the size of each second intercalated hole being larger than the size of the preceding contiguous first intercalated hole.
  • Holes increasing in size in the direction of increasing gas flow are usually used in rotating discs of regulating valves of the prior art, which can give rise to surges in gas flow transition between discrete gas flow positions (the subsequent hole with which the outlet hole overlaps always has a size larger than the preceding hole with which it no longer overlaps). This translates into a non-linearity in gas flow between discrete gas flow regulating positions, and the user will feel that the gas appliance has poor quality and precision.
  • holes with smaller sizes are intercalated in the main series of connecting holes increasing in size, and second intercalated holes with larger sizes than the size of the preceding contiguous intercalated holes are intercalated between each intercalated hole and the subsequent hole of the main series, whereby more linear transitions of the gas flow are obtained, giving rise to a more linear regulation of the flow in both directions for increasing and reducing gas flow.
